Step-by-step explanation:
2.
Step where it was wrong ->
x-8 = 0
x=-8
They just put negative eight on the right side you have to cancel negative 8 out by adding negative 8 on both sides.
x-8=0
+8 +8
x=8 <- Right solution.
3.
Step where it was wrong ->
8(p-7) = 75
8p-7=75
Distributive Property you have to do 8 times p and 8 times -7, they just did 8 times p and forgot to do 8 times -7.
8(p-7)=75
8p-56=75 <- Do 8 * -7 in addition of doing 8 *p
8p=131
/8 /8
p = 16.735 or 131/8
Answer:

144/11 = p
Best of Luck!
4x + 6
3x - 2 = x + 8
x = 5
